TECHNICAL FIELD

The present invention relates to technology of a page/site serverdisclosing Web pages.

This application claims the benefit of priority under the ParisConvention from Japanese patent application No. 2013-196454, filed onSep. 24, 2013, which is incorporated herein by reference in accordancewith PCT rule 20.6.

BACKGROUND ART

In recent years, a huge amount of Web page contents are disclosedthrough the Internet by page/site servers. The page contents are pageswhich many and unspecified third parties can access and which in mostcases include text sentence(s)/document(s). A terminal accesses thepage/site server and displays a part or (if possible) a whole of theobtained page content with a browser. The user of the terminal canbrowse the displayed page then to change the display range by scrolling(page-up/page-down).

Meanwhile, many and unspecified users contribute through the Internet anenormous amount of comments to site servers which process, e.g. SNS(Social Networking Service), blog (weblog) or mini blog (mini weblog)such as Twitter (registered trademark). There are many cases in whichthe posted comments discuss a common topic. For example, therecontributed are many comments that discuss, as the common topic, thecontent of a page content as above-described.

There are conventional technologies which facilitate browsing ofinformation sites which exist on networks. For example, Patent DocumentNo. 1 discloses a technique in which automatically extracted from manyinformation sites and displayed is an information that has a highpossibility of being required by a user. The technique extracts a mainbody text of a title or article from each of the pre-registeredinformation sites and preferentially provides information of informationsites that carry main body texts similar to one another. When a desiredinformation (title) is focused, its main body text is read out andpop-up displayed.

Also, Patent Document No. 2 discloses a technique where, by analyzingtags of HTML (HyperText Markup Language) in blog sites, only main bodiesdescribed by users are extracted from the blog sites. Further,Non-patent Document No. 1 discloses a technique which extractsdescriptions related to the future by analyzing the structure ofsentences of Web news, and then automatically arranges the extractedinformation in the form of a chronological table.

SUMMARY OF THE INVENTION Problem to be Solved by the Invention

The conventional technique described in Patent Document No. 1 isdesigned to display on a terminal the whole of important news articlesreported on plural information sites. The conventional techniquedescribed in Patent Document No. 2 is intended to display on a terminalonly main bodies obtained by excluding such as advertisements andbanners from Web pages. Further, the conventional technique described inNon-patent Document No. 1 is designed to display on a terminal a summarytext generated by extracting portions described on a predeterminedviewpoint from a news article and then summarizing the portions.

All of the above-mentioned conventional techniques require users tobrowse a part of the page content displayed through a browser and thenchange the display range by scrolling thereby to search an noteworthysentence. If the noteworthy sentence appears at the end of the pagecontent, the users have to scroll the page content from the head to theend.

Here, the present inventors focus on prompt display of a noteworthyplace which interests every user in a page content. Especially in thecase of using a terminal such as a smartphone or a tablet-type computer,it is more difficult to promptly display such a noteworthy place becauseof the restriction of the display size even according to theabove-described conventional techniques.

It is therefore an object of the present invention to provide apage/site server, a program and a method for immediately displaying anoteworthy place which interests every user in a page content.

EMBODIMENTS OF THE INVENTION

Illustrative embodiments of the present invention will be describedbelow with reference to the drawings.

FIG. 1 is a configuration diagram schematically illustrating oneembodiment of a system using a page/site server according to the presentinvention.

As shown in FIG. 1, a page/site server 1, a comment server 2, a pagedisclosing server 3 disposed as an option, and terminals 4 areinterconnected through the Internet.

The page/site server 1 is configured to deliver a page content in whichan noteworthy place to be observed is prepared to be displayedimmediately with scrolling the page. The page content is a content whichcan be accessed by many and unspecified users and includes text(s) suchas a news article.

The comment server 2 is a site server which enables plural contributorsto send their text comments to one another. The server 2 may be, forexample, an SNS (Social Networking Service) server, a blog (Web-log)server, a bulletin board server or a review site server. The commentsdisclosed by the comment server 2 are, for example, tweets released onthe Twitter (registered trademark) sites.

As one embodiment, another page disclosing server 3 may be connected tothe Internet under the configuration where a proxy server 1 is disposedat the position of the page/site server. The proxy server 1 serves as aproxy for mediating between the terminal 4 and the page disclosingserver 3 and sends to the terminal 4 a page content delivered from thepage disclosing server 3. To the page content, the proxy server 1attaches a scroll control code used for immediately displaying thenoteworthy place.

The terminal 4 may be, for example, a smartphone, a cellular phone, apersonal computer or the like, which allows a user to browse pagecontents through a browser. The terminal 4 accesses the page/site server1 thereby to display a part or (if possible) the whole of the obtainedpage content with the browser. According to the present invention, thenoteworthy place which interests every user in the page content isdisplayed with the page content scrolled.

The following explanation is premised that, as shown in FIG. 1, thepage/site server 1 and the comment server 2 are separately provided inthe Internet. However, as an alternative, there may be installed a siteserver in which both functions of the page/site server and the commentserver are integrated. The site server enables page contents to bedisclosed in the form of adding a lot of corresponding comments to eachpage content. YouTube (registered trademark) is an example of a servicethat utilizes such a site server.

FIG. 2 is a functional block diagram illustrating one embodiment of apage/site server according to the present invention.

In the embodiment shown in FIG. 2, the page/site server 1 is constructedto include, as well as a communication interface configured to beconnected to the Internet, a page-content storing unit 10, a commentgroup retriever 11, a characteristic word extractor 12, a conceptdictionary 13, a characteristic word retriever 14, a browsing-partdisplay controller 15, and a page content retriever 16. These functionalunits are embodied by executing a corresponding program on a computermounted on the server 1. Further, the processing flow visualized byarrows connecting the functional units in the figure can be understoodas an embodiment of a method for disclosing comments according to thepresent invention.

(Page-content storing unit 10) The page-content storing unit 10 isconfigured to store page contents in advance. The unit 10 may store(URLs (Uniform Resource Locators) of) new page contents gathered byusing, e.g. RSS (Really Simple Syndication/Rich Site Summary).

FIG. 3 is a schematic diagram showing an example of a displayed pagecontent.

According to FIG. 3, there displayed is a page including text and animage, which announces a news whose title is “a Corporation Releases NewPortable Terminal X!”.

(Comment group retriever 11) Returning to FIG. 2, the comment groupretriever 11 is configured to retrieve from within the comment server 2a comment group which includes comments related to a page content. Thepage content, which is stored in the page-content storing unit 10, maybe one which the page content retriever 16 requests based on a pageacquisition request transmitted from a terminal 4. The comment groupretriever 11 uses, e.g. a URL, a title or a hush tag of the page contentas a retrieval key thus to retrieve through a retrieval API (ApplicationProgramming Interface) provided as an interface for the comment server2. For example, in the case that the page content is a news article, thecomment group retriever 11 obtains a comment group including commentswhich are related to the news article and made from many and unspecifiedthird parties. The retrieved comment group is outputted to thecharacteristic word extractor 12.

FIG. 4 is a schematic diagram showing an example of an obtained commentgroup related to the page content illustrated in FIG. 3.

As shown in FIG. 4, there obtained is the following comment grouprelated to the page content shown in FIG. 3.

Page content: “α Corporation Releases New Portable Terminal X!”http://www.a.com/X.html

Comment Group:

“It's amazing performance.”;

“A little high price.”;

“I may buy it, if it's in the 20 thousand-yen range.”;

“I don't buy it.”;

“Wastefully high performance www”;

“α Corporation has this type of value-range.”;

“A bit pricy, but good buy as high cost-effective.”;

“Amazing! α Corporation's new terminal has super high performance(*̂ô*)”;

“What is this? I Want!”;

“I want this. Low price! Maybe I should buy this tomorrow.”;

“Come on wwwwww”; and

“I wish it were a little cheaper.”

(Characteristic word extractor 12) Returning to FIG. 2, thecharacteristic word extractor 12 is configured to extract, from theobtained comment group related to the page content, one or more“characteristic words” that appear in the text of the page content witha high appearance frequency under a predetermined condition. Here, thepredetermined condition may mean that one or more characteristic wordscharacterizing the page content as distinguished from the other ones areextracted by using TF-IDF (Term Frequency-Inverse Document Frequency)method.

The characteristic word extractor 12 is adapted to use morpheme analysisto extract words from the text included in the comment group. The“morpheme analysis” is a technique that divides a sentence into wordseach having a certain meaning and uses dictionaries to determine thepart-of-speech or the content of each of the words. The “morpheme” meansa minimal unit that is a sentence component having a certain meaning.Words that are regarded as characteristic are extracted with TF-IDFmethod from the words extracted by using morpheme analysis. Here, theTF-IDF method is a technique which weights each extracted word toexpress a sentence including the words as a vector by using a query, andranks the extracted words by the degree of similarity between thesentence and the query. The larger the rank value given to an extractedword is, with the higher possibility the extracted word is recognized asa characteristic word. For example, the appearance frequency of each ofthe words included in the title or body of each news article may be usedas a TF, and the appearance frequency of each of the words included inall the news articles may be used as an IDF.

According to FIG. 4, the following “characteristic word” and its“appearance frequency” are detected, for example.

[characteristic word] [appearance frequency] “performance” 3 times“price” 2 times “thousand-yen” 1 time “value” 1 time “cost-effective” 1time “cheap” 1 time

In the just-described example, the characteristic word “performance”,which has the highest appearance frequency, is outputted to thecharacteristic word retriever 14. If a characteristic word with thehighest appearance frequency is not included in the page content,outputted is a characteristic word with the second highest appearancefrequency.

(Concept dictionary 13) Returning to FIG. 2, the concept dictionary 13is configured to hold information describing a conceptual system and,when inputted a word, output a generalized word (broader concept word)of the inputted word. The concept dictionary 13 may be an EDR corpus asdescribed in Non-patent Document No. 2, for example. The EDR corpus is agroup that includes corpus records, each of which is constituted by“headline information”, “sentence component information”, “morphemeinformation”, “sentence construction information” and “semanticinformation”. The semantic information describes a data expressing therelation among concepts in the form of frames and graphs.

As an alternative, the characteristic word extractor 12 may beconfigured to extract a plurality of characteristic words then toconvert these characteristic words into generalized words by using theconcept dictionary 13 and thus to output the generalized word with ahigh appearance frequency as a characteristic word.

In the above-described example, a plurality of characteristic words areconverted into the following generalized words.

[characteristic word]→ [generalized word] “performance” “performance”“price” “value” “thousand-yen” “value” “value” “value” “cost-effective”“value” “cheap” “cheap”

Subsequently, there calculated as follows is the appearance frequency ofeach of the generalized words into which the characteristic words havebeen converted.

[generalized word]→ [appearance frequency] “value” 5 times “performance”3 times “cheap” 1 time

In the just-described example, there outputted to the characteristicword retriever 14 is the generalized word “value” which has the highestappearance frequency (as well as the characteristic words “price”,“thousand yen” and “cost-effective”).

(Characteristic word retriever 14) The characteristic word retriever 14is configured to retrieve a place where the characteristic word appearsin the page content.

Here, when retrieving the appearance place of, e.g. the characteristicword “performance”, the following page-content place is retrieved fromthe page content shown in FIG. 3.

“Supreme ‘Performance’!”

Further, when retrieving the appearance place of, e.g. thecharacteristic word “value”, the following page-content place isretrieved from the same page content shown in FIG. 3.

“The ‘price’ is 3,150 yen, including tax.”

(Browsing-part display controller 15) The browsing-part displaycontroller 15 is configured to control the objective page content to bedisplayed in such a way that the user can browse the appearance place ofthe characteristic word included in the page content. Specifically,there attached to the page content is a scroll-control code which allowsthe noteworthy appearance-place to be displayed immediately.

Practically, either or both of the following two displaying methods maybe adapted.

(Displaying method 1) A page part including the characteristic word ofthe page content is displayed at the top or center of the terminaldisplay area (by direct jump to the top or center), and in the form ofbeing scrolled if needed.(Displaying method 2) The characteristic word of the page content ishighlighted. For example, the characteristic word may be marked with afluorescent color then to be displayed.

FIG. 5 is a schematic diagram showing a first example of displaying apage content by the page disclosing method according to the presentinvention.

In the case that the characteristic word is “performance” included inthe page content shown in FIG. 3, the following place in the pagecontent is displayed at the center of the display area.

“Supreme ‘Performance’!

64-bit CPU included, OS version 5.1,

High resolution comparable to TV display, Camera with high-speedshutter,

What's more Charging cable for charging between smartphones!”

The HTML code of the place including the above-described characteristicword “performance” is as follows.

“...... Supreme </DEFANGED_span id=“highlight” style=“back ground-color:#ffff00”>performance </DEFANGED_span>!<br/> 64-bit CPU included, OSversion 5.1,<br/> High resolution comparable to TV display, Camera withhigh-speed shutter,<br/> ...... ” id=“highlight”: Mark for jumping tothe top (arbitrary character string in the quotation marks)style=“background-color: #ffff00”: Highlighting the character backgroundwith yellow color.

Thus, the sentence line “Supreme Performance!” is searched out anddisplayed by referring to the following URL, for example.

http://server/test.html*highlight

FIG. 6 is a schematic diagram showing a second example of displaying apage content by the page disclosing method according to the presentinvention.

In the case that the characteristic word is “value” included in the pagecontent shown in FIG. 3, the following place in the page content isdisplayed at the center of the display area.

“The ‘price’ is 3,150 yen, including tax. Purchase from the followingshop: Online shop −> The nearest α Corp. shop −> ”

(Page content retriever 16) Returning to FIG. 2, the page contentretriever 16 is configured to receive a page acquisition requesttransmitted from a terminal 4, to retrieve a page content whichsatisfies the request, then to respond to the terminal 4 with theretrieved page content. Here, the page content retriever 16 may transmitto the terminal 4 the comment group itself as well as the retrieved pagecontent. In this case, the user browsing with the terminal 4 can knowwhat comments have been contributed when further browsing the commentgroup. Alternatively, only the transmitted comment group, which includesthe “characteristic word” to be displayed, may be displayed.

FIG. 7 is a functional block diagram illustrating one embodiment of aproxy server according to the present invention.

In the embodiment shown in FIG. 7, a page/site server serves as a proxyserver unlike the embodiment shown in FIG. 2. Accordingly, a pagecontent acquirer 17 is provided instead of the page-content storing unit10 shown in FIG. 2. The page content acquirer 17 is adapted to send apage acquisition request to the page disclosing server 3 then to receivea page content as a response. The proxy server 1 attaches to the pagecontent a scroll control code used for immediately displaying thenoteworthy place to be noticed, then to send to the terminal 4 the pagecontent as a response.

As explained above in detail, The page/site server, the program and themethod according to the present invention allows immediately displayinga noteworthy place of a page content, which interests every user.Especially, when using a terminal such as a smartphone or a tablet-typecomputer to display a page content, the user can easily browse thenoteworthy place without being affected by the limited display screensize.
